PIERRE JURY, FILS, AND EDOUARD ANGER, OF PARIS, FRANCE.

TOOL FOR WORKING WOOD, 80c.

SPECIFICATION forming part of Letters Batent No. 564,753, dated July 28, 1896.

pp i ati n fil n y 9, 1896. 7 Serial No. 574,899. (No model.) Patented in France May 17, 1895, No. 247,494.

To all whom it may concern:

Be it known that we, PIERRE JURY, Fils, and EDOUARD ANGER, of the city of Paris, France, have invented an Improved Tool for \Vorking-Wood, Marble, Metals, and other Materials, (for which we have obtained Letters Patent in France for fifteen years, dated May 17, 1895, No. 247,494,) of which the following is a full, clear, and exact description.

In the working of wood, for example, when using a somewhatheavy or cumbersome piece, such piece cannot be shaped by the machines in ordinary use, which are fixtures; that is, the case with a staircase string-board or with an arm-chair. The invention forming the subject of the present application for patent relates to an arrangement of rotary tool, essentially movable, operated' by a mechanical motor conducted and directed by the workman, and having no bearing-point other than the materialto be worked.

A method of carrying our invention into effectis illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a complete apparatus constructed according to our invention as applied to the working of wood. Fig. 2 is a plan of Fig. 1. Fig. 3 is a transverse section drawn on the line 1 2 of Fig. 1. Fig. at shows separately a longitudinal section of the details of the tool-carrying shaft re- Fig. 5 shows separately the key for rotating the shaft upon which the tool-carrier is screwed.

In the various figures similar letters of reference indicate like parts.

As will be seen in the drawings, this apparatus consists of a framing Ct, furnished at ing a carries two blocks is, whose bearings receive the tool-carrying shaft 1. This shaft carries the pulley m and is hollow throughout its entire length. One part of its bore is cylindrical to receive the shaft n, which has at one of its ends a screw-threaded part 0, screwing into one end of the tool-carrier p. The other part of the bore of the tool-carrying shaft Z is conical and serves to receive the corresponding part of the tool-carrier p, which receives the tool or cutter q, properly so-called, which is fixed thereto by means of a screw 1". The key 8 has a small square part fitting a corresponding space t,formed in the outer end of the shaft 01.

Rotary motion of the tool-carrier is obtained by cord or strap, or by means of one or several transmitting-gearings fixed to the apparatus itself or in the neighborhood of the piece to be worked. It may also be obtained directly by a motor operated by electricity, compressed air, or steam, or by a turbine or other motor fixed to the apparatus itself in any convenient manner.

From the foregoing it will be understood that v the apparatus, being held in the hands by the handles 1) and the tool q being rotated, the material to be worked will be placed between the contact-guides h, which will have been regulated by means of the screws 6 and g, so that the faces of the contact-guides It will follow the outlines of the piece to be worked.

In order to prevent the tool q when working from penetrating too suddenly in the material, the contact-guides it give way transversely, thus compressing the springs, and the action of these springs in tending to extend balances the weight of the apparatus.

To change the tool, the tool-carrier p is unscrewed by turning the shaft n by means of the key 8.

The tool-carrier may receive either a nulling-tool, a grinding-wheel, a brush, or other tools appropriate to the kind of work to be produced and to the nature of the material to be worked.

We would have it understood that the forms, arrangements, (shaft, vertical, horizontal, or inclinable in any direction,) dimensions, details, accessories, and materials employed for the construction of our apparatus may be varied without departing from the peculiar character of our invention.

We claim- 1. In combination, the tool, the main frame having handles, the adjustable carriages cl thereon, and the adjustable slides f on the carriage and the contact-guides h carried by the said slides f.

2. In combination, a rotary cutter, the frame having handles, the adjustable carriages cl on the frame, the slides f adjustable on the carriages and the yielding contact-guides h extending from the slides to act in conjunction with the cutter, substantially as described.

3. In an arrangement of rotary tool for working wood, marble, metals and other materials herein described the combination of a hollow tool-carrying shaft l,a pulley m mounted on said shaft, bearing-blocks for carrying the shaft Z, a cylindrical portion of the bore of said shaft to receive the shaft 91 a screwed end to the shaft or screwing into the tool-carrier p, a conical portion of the bore of shaft Z to receive the conical part of the tool-carrier p which receives the tool or cutter q properly so called, a screw 0" for fixing such tool or cutter in its holder and a recess 6 in the outer end of the shaft or to receive the square end of the key 8 substantially as herein shown and described.

The foregoing specification of our improved tool for working wood, marble, metals, and other materials signed by us this 19th day of December, 1895.
